The clamps worked like they should. The thing issue is I wish the banding should be a little thicker..But it seems ok we will see down the road.

Its not polished stainless and it seems a bit soft. Probably plated not solud but i needed an adapter and fit is great and much cheaper than parts store

I used this as a bearing dust cap driver for the 2.44 dust caps on my boat trailer. It fit perfectly and worked perfectly for that purpose. I used a piece of 3/4 plywood about 4" square to place between this adapter and the hammer. Whack, whack the dust cap went in.

This is an exhaust adapter. It’s all metal. It is 2 inch inner diameter on one side and 1 7/8 inch inner diameter on the other side. It’s a little over three and a half inches long. Definitely measure before you get it but if this is the size you need then great. Good find.

Had to cut my exhaust off after the engine while doing extensive work on my suspension and used one of these to help me reconnect it when I was done. Made the job a lot easier than I originally expected. Slid right on to each half, and is deep enough that it stayed together while I played with positioning downstream to get the exhaust to hang where I wanted before tacking together and removing everything to fully weld. Very satisfied with this and if I ever have to do this again I'll be getting another because it is SO MUCH easier than trying to butt weld two identical pipes together or creating my own taper by slitting the bending the end of the tube down to fit inside the other.Maybe it is not as clean, but it gets the job done!
